Free date and age calculators

Simple, private calculators for ages, birthdays and the time between dates. Every result comes with a plain-English explanation of how it was worked out.

Age Calculator

Find your exact age in years, months and days, plus your next birthday countdown.

Days Between Dates Calculator

Find the exact number of days, weeks and months between any two dates.

How these calculators work

Dates are counted using calendar-accurate day arithmetic, so month lengths and leap years are handled correctly rather than assumed to be a fixed number of days.

Everything is calculated in your browser. The dates you enter are not sent to our servers or stored.
